SMA Female to UHF Female Adapter

Description

The SMA Female to UHF Female Adapter is a specialized “between-series” RF component designed to provide a high-reliability transition between the high-precision SMA standard and the widely utilized UHF interface. It features an SMA Jack (Female) on one side, utilizing a standard fine-threaded external interface and internal socket, and a UHF Jack (Female/SO-239) on the other, featuring the classic large-format threaded external housing and internal socket.

This adapter is indispensable for operators and technicians who need to join SMA male and UHF male (PL-259) cable assemblies. It serves as a high-quality coupler, allowing for versatile connectivity between modern microwave modules and legacy high-power broadcast equipment. While the SMA interface is a precision connector rated for higher frequencies, the UHF side provides a rugged connection for applications typically below 300 MHz. Constructed with a heavy-duty nickel-plated brass body and PTFE (Teflon) insulation, it maintains reliable mechanical and electrical contact in both mobile and stationary installations.

Key Technical Advantages

• Interface Compatibility: Enables seamless interoperability between high-precision SMA components and traditional UHF-based communication hardware.

• Dual-Socket Coupler: Serves as a reliable link for joining two different male cable standards in a single, compact, and rugged unit.

• Rugged Mechanical Stability: The solid brass construction and threaded interfaces ensure a stable connection capable of withstanding physical stress and vibration.

• Superior RF Shielding: The solid metal housing provides a continuous ground path, ensuring stable performance and protecting against signal leakage.

• Maximum Conductivity: High-purity gold or silver plating on the internal center contact sockets ensures ultra-low contact resistance and long-term protection against oxidation.

Key Features

• SMA Female to UHF Female Interface: Consists of an SMA Jack (with socket and external threads) and a UHF Jack (with socket and external threads).

• Nickel-Plated Brass Body: Offers superior corrosion resistance and professional-grade durability for indoor and outdoor applications.

• Premium PTFE Dielectric: Offers high thermal stability and maintains consistent electrical performance across its operating range.

• Industrial Durability: Rated for at least 500 mating cycles, ensuring long-term reliability in field and laboratory environments.

• Standard Compatibility: Fully compatible with all standard PL-259 (UHF Male) and SMA Male connectors.
